Ted holds litter-5 siblings Jerri (gray) and Randy (buff), while younger Berry (black outline) hovers behind Jerri.
Berry was always a step or three behind his unrelated litter-mates. We thought he was developmentally-challenged and likely to be run over or eaten if his adopter let him outside. So we decided to keep him.
It turns out he was just slow. Now he's 50K staff feline Yogi, aka Yogermeister.
